Abbott immediately filed an appeal after a federal judge ruled parts of the abortion law unconstitutional.

"It's easy to say we want them to fulfill all their hopes and dreams," Davis said. "But when it comes time to make a commitment to these kids, the state is falling short."

Dubbed "Great Start: Great Texas," the plan calls for ensuring that every child in Texas has access to pre-kindergarten classes, and promotes early-childhood reading so every child is reading at grade-level by 3rd-grade.

Introducing the third plank of her education platform, the Fort Worth state senator called for "going beyond" simply restoring $200 million in state grants for early education programs that was cut by the 2011 Legislature. Her plan includes introducing a sliding scale for families with incomes above 185 percent of the federal poverty level and switching the state's focus from three-hour to full-day schedules. She said the proposal's implementation cost of up to $1 billion would come from surplus revenues.

Pointing to research that shows the quality of early education is a strong indicator of future income, Davis predicted big payoffs for the Texas economy.

"It begins by ensuring every Texas child has access to full-day, all-day PreK," she said.

The campaign of Attorney General Greg Abbott, the presumptive Republican frontrunner for governor, dismissed Davis' proposal as "fuzzy."

"Sen. Wendy Davis' education proposals are mere talking points, not an actual plan that presents or explains how much her proposals will cost and how she plans to pay for them," Abbott spokesman Avdiel Huerta wrote in an emailed statement. "The only thing definitive in Sen. Davis' fuzzy proposal is that it will add billions in new spending with unfunded promises."
